Door close reminders and refrigerators

Abstract

The invention discloses a door closing reminding device and a refrigerator. The door closing reminding device is arranged between a box body and a box door, and comprises a closed air bag, an air pressure sensor and a prompter, wherein the closed air bag is arranged between the box body and the box door and has elasticity; the air pressure sensor is used for detecting the air pressure in the air bag; the prompter is connected with the air pressure sensor. According to the technical scheme disclosed by the invention, the air pressure in the air bag between the box body and the box door of the refrigerator is detected by virtue of the air pressure sensor, so as to judge whether the box body and the box door are normally closed and remind a user through the prompter. The phenomenon that the temperature in the box body rises due to cold leakage caused by the unclosed box door is avoided, the temperature in the refrigerator can be ensured to meet the set requirements, and meanwhile, huge waste of an energy source due to the fact that a compressor is in a starting-up state for a long period of time is also completely eradicated.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a door closing reminder device and a refrigerator. Background technique [0002] A refrigerator is a device that relies on low temperature to preserve food. In order to keep the refrigerator in a low temperature state, the box and the door on the box should be closed when the items are not stored. The usual practice is to inlay door seal magnetic strips around the frame of the box door, and rely on the door seal magnetic strips to closely adhere to the opening surface of the box made of metal plates to close the box and the door, thereby preventing the box from Heat exchange inside and outside. [0003] When accessing items, the user only needs to pull the door handle hard, and the box door can be opened by relying on the pulling force to overcome the attractive force between the box door and the box body. After accessing the items, gently push the door to the closed posi...

Problems solved by technology

[0004] However, when the user closes the door, the phenomenon of "false closing" of the door often occurs because the door is not pushed in place, that is, the door is basically in the closed position, but the magnetic strip of the door seal is not attracted to the box body

This phenomenon is not easy to be discovered by the user, resulting in long-term cold leakage at the door seal, and the temperature inside the box rises, making it impossible to ensure that the temperature inside the box meets the set requirements; Power-on state, resulting in a huge waste of energy
